### how many ways are there to add and get the sum of 180

There are an infinite number of ways to get 180 from two numbers, if we count decimals and fractions as well as other real numbers; but if we are limited to positive integers greater than zero and just the sum of two of them, we are limited to x and 180-x. If we also exclude 90+90 because

### Find the n th term and sun upto n terms of the series 1+(1+2)+(1+2+3)+........

Take two consecutive terms kth and (k+1)th: k(k+1)/2 + (k-1)k/2=(k^2+k+k^2-k)/2=k^2. So, taken in pairs, the sum=sum of squares of natural numbers. [1+(1+2)]=2^2; [(1+2)+(1+2+3)]=3^2, etc.  Let's work out the first few terms of the series: 1, 1+3=4, 1+3+6=10, 1+3+6+10=20, 1+3+6+10+15=35

### Find the explicit expression for the sequence: 1.5, 1.6, 1.8, 2.1, 2.5

The common difference of this series is 0.1n, because the differences are 0.1, 0.2, 0.3, 0.4. a1=a0+0.1, a2=a1+0.2, a3=a2+0.3,..., a(n)=a(n-1)+0.1n. If we subtract 1.5 from each term, we get: 0, 0.1, 0.3, 0.6, 1.0. This is 0, 0+0.1, 0+0.1+0.2, 0+0.1+0.2+0.3, 0+0.1+0.2+0.3+0.4. This is the same

### Prove that no matter what the real numbers 'a' & 'b' are... (scroll for full Q. related to A.P.)

The difference between consecutive terms is a+nb-(a+(n-1)b) = a+nb-a-nb+b = b. So there is a fixed number b between each term, which is the definition of an arithmetic progression, each term increasing by the same amount from term to term. The first term in the sequence would be a if the sequence st

### prove that sin(A+2B)+sin(B+2C)-sin(C+2A)=4sin(A-B)/2.cos(B-C)/2.cos(C-A)/2

First, since the equation is an identity, it has to be true for all values of A, B and C, so let A=B=C, then we have: sin(3A)+sin(3A)-sin(3A)=4sin(0)cos(0)cos(0), which reduces to sin(3A)=0 which is not an identity but has a particular solution of A=n(pi)/3, where n is an integer. Therefore, t

### area of a region between two curves?

The picture below shows the required area between the two curves: y=e^(-x^2) (red) and y=1-cos(x) (blue). The vertical blue line shows the limit of the first quadrant (x=(pi)/2). Each grid square in the picture has an area of 0.04 and the area is roughly 14 complete squares: 14*0.04=0.56 is a rough

### Given an arithmetic progression with Asub50=10 and Asub100 = -10. Find d and Ssub50

Between the two terms the total difference, where d=difference between consecutive terms, is (100-50)d=-10-10=-20. So d=-20/50=-2/5=-0.4. The difference between Asub50 and Asub0 is the same as between Asub100 and Asub50, that is, -20, so Asub50-Asub0=-20; 10-Asub0=-20, and Asub0=30, the
